M U A uuuuu 2/7" packers or plunger-s operate simultancousl y and bringthe cigarettes together in two super woed layers in which the cigaretteslie in close contact with each other.

The action of the packers brings the cigarettes into position in frontof the plungets working longitutlinully oi the machine and by thereplttngers the two superposed layers of cigarettes are carried forward tothe wrapping devices. Tlte wntppcrs are arranged in a pile in a suitableholder and thewntppcr feed devices remove the wrappers singly from thebottom of the pile, a wrapper being removed from the pile for eachquantity of cigarettes advanced by the plungers. The wrapper feedingdeviccsdrop the wrapper upon suitable positioning devices by which thewrapper is supported directlyin the path of the advancing cigarettes,'so that the continued advance of the cigarettes in its the initialfolil of the wrapper about the cigarettes and then the cigarette" withthe wrapper partially folded around them are forced forward so thatpasting devices may apply past/ to suitable portions of the wrapper andthe wrapper folding devices proper may complete the folding oi thewrapper and seal the package. The completed packages are then dischargedfrom the machine by intermittently operative devices which force thecompleted packages downward through the discharge chute of the machine.

Boferring'now to the drawings, and particularly to 1 and 2 1 designabeeastand or table of suitable construction upon which the moving parts ofthe machine aremounted. This table is slotted longitudinally M2, to forma guide for a slide 3 which carries several sets of plungers. Themechanism for operating the slide 3 comprises'a long slotted lever 4pivoted at the bottom oithe table or stand l, a link 5 to connect thelever with the slide, and a crank 6, having its pin 7 working in theslot 8 of the lever and secured-upon the main driving shaft 9 of themachine. Power may be applied to the I f main driving shaft in anysuitable manner and a pulley 10 is provided to receive power which istransmitted to do main driving shaft through reducing gearingcompriingthepinionsloandlo".

' The receiving hopper 11, is mounted about midway i between the endsofthe stand or tablel and extends transversely thereof. The upper section12 of the front wall of the hopper is pivoted'to afiord better access tothe cigarettes'in the hopper and at the bottom of the hopper arethe' twogroups of receiving chambers '13 and 14. To'insure the proper entry ofthe cigarettes into' these receiving chambers an agitating device is'provided. This consists of a iram'e 15 extending tninsversely ofthemachine, inclined wings 16 which converge downwardly, ands separator 17in the middle of vthe friune 15 which has the form of an inverted wedge.

- Rgciprocatory movement is imparted to the frame ubottom .of thehopper. The devices by which reciprocatory movemont is imparted to theframe 15 are best seen in Figs. 1 and 6. Power is transmitted from..,the main driving shaft to a secondary shaft 18 by means of bevel gearwheels 19 and 20, and from the secondary draft 18 power is transmittedthrough bevel gent 'wheels I 21 and 2'. averticnl shaft 23 provided atitsuppor end i with a disk and wrist pin 24 from which movement is limparted to thrl'ramc If: by a link 25 connected with l a bracket 26secured to one end of the fratro.

The slide 3 carrics two sets of short plungcrs 2'1 and 28, respectively,which arc adapted to pass through thc rccciving chambers 13 and H,rt-stm-tivcly, as tho slith- 3 nears the end of its forward mtwcmcnt.'lhcso plungcrs force the bottom layer of cigarottcs out of (lKll groupof chambers, the cigarettes from the chambcrs l2! advance into thepacking chamber 29 and 'thosc from the chambers 14 advance into thopacking chambcr 30. As bcst shown in Fig. 3, the inner cnds of thetwopackiug chambers ovcrlap, and packing plungcrs or packcrs 31 and 32are arranged for rcciprocatory movement in the packing chamber s. By thcaction' of these packers the cigarettes are brought together in twosuperposed layers at the inner ends of the packing chambers where theylie directly in the path of a pair of long pl'ungcrs 33 and 34 carricdby the slide 3.

The mechanism for imparting movement to the packers 31 and 32 is bestshown in Figs. 8 and 4. A cam 35 on the shaft 18 operates a lever 36which carries at its lowcrcnd a roller 37 which lies in a groove'38 onthe face of the cam. At its upper end thelcver 56 is con nected by meansof a link 39 with 'aslide 40 to which the packer 31 is secured. Thisslide 4 0 is supported block 42 in which the lower packing ohamber 30 isslide 46 carries the. packer 32. Consequently, the movement of the slide40 and the packer 31 under the 'posite movement-of the slide 46 and thepacket 32. The movements of the packers arc, of course, so timed thatthe inward movements take place after the retraction of the plungors33-and'34 from-the packing chambers,.and during the initial partof theadvance of the plungers 33 and 34 the packers 3] and 32 stationary intheir innermost. positions, thus holdi g ,the cigarettes in the-packingchambers 29 and- 30 in proper position to be engaged by the plungers 38and 34 and carried forward into the pqssagedfi which lies diroctly infront of the overlappin gjniier ends of the Pee ing chambers.

so that t-he'arrangement of' the cigarett'eewill not be formed. 0n theunder side of the slide til-is secured a rack bar-43 whichextends'through a guide-way formed in the block 42 and this rack barengages a small pinion 44 mounted midwayjbe'tweeir the ends". oftheblock 42.- ;The pinion 44 also nioahes with a rack bar 46 which is tothe under side 0! a slide 46 which is supported and guidedby a pair ofrods 47." arranged directly opposite the guide 41 :This

' altered in pacing out of the packing chambers into the by a pair ofguide rods 41 projecting laterally from the action of the lever 36 isaccompanied by adirectly 014-" n will be bmvte um nets-inn between thoven lapping portions of the pac'lting' chambers is very thin,

the guide-way fiO'until arnrstcd by pins 52 projecting int the guide way50, said pins being adjustable and l so as to eff ct the sealing of thewrapper will be ch arly connected with the nuts 5] by' means of whichthey may be fastened in position.

fl ojfeeding devices by means of which the wrappers 'ftinovcd one by onefrom the pile are shown in 1, 2 and 7. As shown in Fig. 2 and Fig. 7, apair of belts are arranged beneath the pile of wrappers, the bottom ofthe wrapper holder being slotted to permit the belts to come in contactwith the-bottom wrapper in the pile. 'lhese belts 53 are supported onsuitable rollers or pulleys 54 and are preferably made of rubber toinsure sullicicnt friction between the belts and the wrappers to bewithdrawn from the pile. Intermittent. motion is imparted to the bolts53 and the action of the belts is so; timed that a wrapper is alwaysdischarged into the guide way50and positioned upon the supporting pins52 before the advance of a quantity of cigarettes C, as shown in Fig.19. The power for operating the feeding devices is supplied from theshaft 18 from whichit is transmitted through bevel pinions 55 and 56 toa vertical shaft 57, the upper portion of which is inclosed in a housing58. Near the.

. upper end of the shaft 57 isa bevel gear 59 which'rnrshcs with a smallhovel pinion 60 on a horizontal shaft til which supports one of a pairof feed rollers 62. The shaft 61 bears a pinion 63 which meshes withanother pinion (54 secured on the axis of the lower pulley54 over whichthe belts 53 run. -The pinion 63 is loose on the shaft. 61, beingsecured to a sleeve 65 which is notched or toothed at one end tocooperate with a sliding sleeve 06 splined on the main shaft to form aclutch. '1 he sliding sleeve 66 is moved to and fro by means of u. lever67 which engages a cam 69 on the shaft 57. The shaft 57 is rotatedcontinuously by means of the pinions 55 and 56 and continuous rotationis imparted through the bevel gears 59 and 60 to the shaft 61 and embers63' and 66 out of engagement except at the pro or time to effect thedischarge of a wrapper from the 'lcin thewrappcr holder. Therithe cam 69allows the cl tch members to engage and impart movement to the lo 'crpulley 54, from which it is transmitted to the bolts 53 iich act. uponthe bottom wrapper in the pile and cause i to pass forward and downwardto the feed roller (52 by which it is carried tothe guide way 50. Theremoval dbmore than one wrapper froin the pile at each opt:ration of thefeeding belts is prevented by 7 means of suitable stops. These stopscomprise the bent gage rod 70 and a pair of rubber fingers 71 carried byinclined supporting members 72 attached to the pivotcd arms 73. Therubber fingers are so positioned that they rest upon the upper surfaceof the wrapper drawn from the bottom of the pile by the belts, and ifseveral wrappcrs adhere together and are carried forward-Jr the belts,the frictional engagementofthe rubber fingers with the overlying wmpperswill separate them from the bottom wrapper which is carried forward onaccount of the greater friction developed betwecn'it and the feed bilts.

The series of operations by which the wrapper is folded around thecigarettes so as to form a compltto. package is ilh stratcd in Figs. 10to 15 inclusive and by reference to Figs. 1 and 2 the application ofpaste or other adhesive to suitable portions of the wrapper to feedrollers 62; but the cam 69 keeps the clutch understood. The initial foldof the wrapper about the cigarettes is effected by the pressure of theends the cigarettes against the wrapper as it is held on thb supportingpins 52 near the bottom of the vertical guide way. The continued advanceof the cigarettes under the action of the plnngers 33 and 34 carries thewrapper forward into the folding box 74, the top and bot.- tom of whichbend the wrapper as the cigarettes pass into the box so as to bring thewrapper in contact with the cigarettes both above and below. After thecigarettes and wrapper enter the folding box the first or downward sidefolds are made, by the inclined ioltlt-l's 75, thus bringing the packageinto the condition shown in Figs. 11 and 12. Further progress of thewrapper and cigarettes through the folding box effects the second orupward side folds through the agen y of the upwardly inclined foldersTti. The last folding action that takes place in the folding box is theinward bending of the flaps to, which is brought. about by small knobs77 carried by spring lingers T8 and extending through the side of thefolding box. After passing through the folding ln x the partiallycompleted package is left in the upper portion of the discharge chu'te79 through which it passes to receiving devices below. The paste orother adhesive for securing the parts of the package is applied to theside portions 11/ of the wrapper as it. msses through the folding boxand the means provided for applying the paste or other adhesive consistsof a pair of suitably mounted wheels 80 to which the paste is suppliedfrom a roller 81. The roller 81 and a smaller roller 82; together witha'doctor 83 arranged between the two rollers, serve as a receptacle forthe adhesive. ers and the doctor are supported in a suitable frnme 84above the folding box and the two rollers are rotafi'd continuously,power being supplied from the shaft 18 through bevel pinions 85 and 86to a vertical shaft 87 from which motion is transmitted throughbcvelpinions 88 and 89 to the roller 82. lntcrntcshing gears 90 and 91 serveto transmit motion to the roller 81 and an additional pinion 92 on theshaft. carrying the paste wheels 80 transmits motion from the pinion 91to the paste wheels. After the partially completed package is forcedfrom the folding box into I the discharge chute 79 paste is applied nthe upper surface of the package at w to secure the end llnp in place.The means employed for applying this paste is a roller 93 carried by aswinging arm EH. This roller is brought into contact with the pasteroller 82 by means of a reciprocating follower 95'which serves thedouble function of raising the roller 93 into contact with the pasteroller 82 on its upward stroke and dcprcssing the packages in thedischarge clnue on its downward stroke. As shown in Fig. 2, the follower95 has an opening through which the roller 93 pmjeets sufliciently tocome in contact with the package immovement.

mediately neath the follower 95 toward the end of its downwa Thecondition of the package at the time it. passes into the discharge chuteis illustrated in FiiLJfrimd the folding and seiiling of the :flap to tocomplete tho package is offected'in the discharge chute. The downwardmovement of the follower 95 not only permits lloth the rollhc roller 93to come in contact with the package and apply a paste at 10, but byforcing the package downward below the level of the folding box, asshown in Fig. 14, effects the first bending of the end flap which isshown in the same figure. The final b nding and sealing of the end flapis effected after the rise of the follower 95 by the next package whichis forced from the folding box into the discharge chute, as shown in Flg. 15.

The passage of the paCnges through the discharge chute is slow and thedi: charge chute is so constructed that a considerable amount ofpressure is required to l'orce the packages through it. The object ofthis construction is to insure the setting of the paste or adhesivebefore the packages are discharged from the inachinc upon-the receivingdevices below. The force required for carrying the packages downwardthrough the discharge chute is supplied by the follower 95 which isattached to a reciprocating bar 96 working iu guides 97 adjacent to thechute. Movement is imparted to this bar from the shaft 18 by means of alink 98 attached to an eccentrieally mounted screw 99 in the end of theshaft, a lever 100 and a link 101 connecting the lever with the bar 96.A pair of oppositely arranged belts are mounted on rollers 103 placed inthe sides of the discharge chute. Thesebelts prevent the rubbing of thepackages against the sides of the discharge-chute and, being preferablyof rubber, yield sufiiciently to permit the e of packages of slightlydifferent size through the discharge chute without distortion As thepackages are discharged one by one from the chute 79, they fall u'ponarcceiving belt 104 arranged horizontally beneath the discharge chuteand actuated frorncthe shaft 18 by means of bevel' pinions 105 and 1 06,which transmit motion to the transverse shaft 1 07, the spur pinion 108carried by the shaft 107 and I the intermeshing spur gear 109 on theshaft 110 carrying one end pulley or roller upon which the belt 104 issupported. The packages are carried bythe receiving belt IO-f to anydesired point of delivery.

' in any way. Each article is removed from one ofthe I From the forgoingdescription taken with the abcompanying drawing, it will be'observedthat themachine as a whole is very simple and the parts are soconstructed and arranged that the machine is not liable to breakage orinjury in use. It will also be observed that the articles to be wrappedare never subjected to treatment which is apt to break or distort themreceiving chambers beneath the supply hopper independe'ntly of-sveryother article and there is no rubbing of the articles lgainst each other'during the action ,of

After thearticles at the bottoms of the receiving chambers are removed, eachgroup of articles so removed is subjected to lateral presume by whichall the articles in the group are brought in close contact preparatoryto the of the plunger: by which the articles are presented to thewrapper. Each group of articles lonns a layer separate from andindependent of the other group and even when both layers are out of thepacking chambers simultaneously by the plungers and brought togethsr'insuperposed layers, there is no rubbing of one layer of articles over theThe invention having thus been described, what is 1.
